Filed: 1997-09-19
Abstract: PROBLEM TO BE SOLVED: To realize a robust dead time correction by determining the polarity from a command current when the effect of switching noise is not negligible or from a 1 sample lag current using a disconnector having a predetermined hysteresis band being set in the vicinity of zero output current. SOLUTION: A hydrid decision unit makes a decision whether the detection current Iafb of phase A out of three phases falls within a hysteresis band Hband or not. O is outputted when it falls within the hysteresis band and the current polarity is determined from a noise free command current Ia*, otherwise 1 is outputted and the polarity is determined from a detection current. A switch SW is operated based on the decision value such that the detection current Iafb is passed to a polarity decision generator thus outputting a polarity decision value for decision value 1 whereas a command current Ia* is passed to the polarity decision generator thus outputting a polarity decision value for decision value O.  In the following stage, the polarity decision value is multiplied by a correction voltage value of dead time and added to the voltage command value Va * of phase A before being inputted to a PWM INV.
